what is thc?

Of the more than 100 cannabinoids in the cannabis plant, tetrahydrocannabinol (THC) is the one principally responsible for the psychoactive and intoxicating effects of cannabis consumption.

THC interacts with the body’s endocannabinoid system (ECS). Put simply, your ECS is made up of two things:

1) Cannabinoid receptors, present in nearly every region of your central nervous system and brain, as well as many other areas of the body, including your immune system; and

2) Cannabinoids that you naturally produce (called endocannabinoids).

Your natural endocannabinoids fit into your ECS receptors like a key in a lock and help carry messages from cell to cell. THC works the same way, temporarily replacing your own endocannabinoids, but with different effects. These may include:

  • the release of dopamine, resulting in feelings of relaxation;

  • a physical response, such as reduced inflammation or an increase in hunger; and

  • effects on various regions of the brain, including the hippocampus (memory), the frontal cortex (thinking and decision-making) and the cerebellum (physical movement and coordination).

    THC content is expressed in milligrams per gram (mg/g) or as a percentage of milligrams per gram of cannabis. For example, if a product is labelled 15% THC and 150 mg/g, it has 150 milligrams of THC per gram of cannabis. It is impossible to have dried flower cannabis with 100% THC, but cannabis extracts (which have been distilled) can have up to 90% THC.

    The effects of THC will be different for everyone. When choosing a product, consider not only the THC potency potential, but also the method and amount of consumption along with personal factors such as your age, your sex, your health history and previous experience with cannabis. Consult with your physician if you have questions.

    • Consuming small amounts of THC can produce effects such as relaxation, heightened happiness, arousal and creativity, more sociability and energy, and an increased appetite

    • However, consuming large amounts of THC may produce overwhelming, unpleasant or harmful effects

    • Consider products with low THC potency and/or at least a 1:1 ratio of THC to CBD (cannabidiol) to help reduce the likelihood of unintended effects. Remember to consume it slowly and in small amounts.

    • Remember that even the same products can vary between lots of the same strain. Please check labels carefully to be sure of the actual THC content in the product you selected.
